Expressing anguish over terrorist attacks in different parts of the country, Congress president Sonia Gandhi cautioned the state governments on Saturday to ensure that anti-terror measures should not lead to polarisation of society. No community should feel under seige because of such actions, she said.

Addressing a conclave of Congress chief ministers, she said there should be no compromise on internal security and all states should have fully motivated forces to combat terrorism.

Observing that the terror attacks in different parts of the country were a cause of 'serious concern and anguish', she said the anti-terror measures should not lead to polarisation of society.

The two-day meeting is being attended by Prime Minister Manmohan Singh, several Union ministers, 14 Congress chief ministers, and senior party leaders.
